Title: Reverse Engineering for Determining Residual Workpiece Geometry in Milling Process
Keywords:

Abstract: Tool breakage during of milling a part with complex geometry could be very unpleasant, because it can lead to a significant delay in the planned processing time which in turn delays the execution of subsequent tasks in the machine queue. Even if the integrity of the part is not affected by the unforeseen events during the milling process, situations can be created that are challenging to solve so that the work process can be resumed at the required pace. Nowadays, the CNC machines allows the machine working without human presence for a long period of time. Loading a set of programs and night operation of the machine is a common practice. This, in turn, can lead to the encountering of specific problems. An example for such problem is a cutting tool breakage during rest milling operations which leads to unidentified residual stock. In this operations tools with smaller diameter are normally in use, which however, should take a relatively large amount of material and this could easily lead to a break. These operations are more often related with great amount of machining time and the complete repetition of the program is not preferred. The complex shape does not allow the measurement of residual material in a conventional way and alternative methods are required in order to create new tool path that could guarantee collision free operation on the on hand and optimization of the machining time on the other hand.
